If you really dislike cleaning the EGR/intake port that often, why not swap in a 2GR-FE? In terms of EGR I'm assuming you mean they replaced external EGR systems with internal versions via variable...

Granted, they do coke up a bit, but imle they tend to last as long as oxygen sensors and other wearable emissions equipment. I had about 130k miles before I replaced mine, and the intake did not have...

Yeah, I've seen plenty of systems, but it seems that manufacturers tend to shy away because of the need for refilling the system with water and the potential for something to screw up and inject a...

Check this (https://cat.inist.fr/?aModele=afficheN&cpsidt=16124609) out.
The point being that EGR has limits with every engine and fuel. If it didn't we could ideally route as much exhaust as...

Eh... It makes the average intake/cylinder temperature higher because exhaust is hotter, but it reduces the peak cylinder temperature because the intake charge contains less oxygen per volume. If too...

I've posted this (https://epa.gov/otaq/presentations/sae-2002-01-2743.pdf#search=%22%22pumping%20losses%22%20epa%22)before, and when using a 1.9L TDI modified for SI and PFI, the maximum EGR rate was...

MetroMPG, from what I've gathered, the appropriate amount of EGR reduces peak flame temperatures/NOx during combustion because it minimizes the amount of oxygen in the combustion chamber, but it has...

I'd guess it would. The only things the turbo does are improving power in proportion to increased air flow and efficiency by a small bit. For any car it'd probably be easier to scrap the current ECU...

The only problem is the octane rating of gasoline, which limits the reduction in pumping losses available from EGR. The nice this is that excessive EGR used with light turbocharging and a fuel with...
